Description

  The present invention relates to a surface construction method using a phosphate-based solidifying material containing a phosphate and an oxide as a solidifying component.

  Phosphate-based solidified materials containing phosphate and oxide as solidifying components (see, for example, Patent Documents 1 to 3) are cured by mixing with water, and the cured product is made of concrete or mortar. Compared with cement-based solidified material, strength (compressive strength, bending strength and tensile strength) and durability (slip / impact wear resistance, fire / heat resistance, resistance to salt / chemical resistance, low chloride ion permeability, acid resistance / In addition to being excellent in alkali resistance and corrosion resistance of reinforcing steel, it is characterized by substantially no cure shrinkage and extremely excellent adhesion to the target surface.

  Further, the cured product of the solidified slurry is excellent in toughness (bending with bending and returning to its original state), low water absorption, water impermeability, heat insulation, and odorlessness (because it is inorganic).

  Furthermore, the above solidified slurry has a very short time to reach practical strength after casting (early strength), can be applied below freezing and in water, and can be applied to almost anything other than plastic and stainless steel without a primer. It also has features such as adhesion.

<Phosphate solidification material>
In the present invention, the phosphate solidified material used as a molded body, an adhesive, or a joint agent contains phosphate and oxide as a solidifying component, and is mixed with water and used as a solidified slurry. This solidified slurry forms a phosphate hydrate ceramic by a reaction exemplified by the following reaction formula (when the oxide is magnesium oxide and the phosphate is potassium dihydrogen phosphate), and is hardened.
MgO + KH ₂ PO ₄ + 5H ₂ O → MgKPO ₄ · 6H ₂ O (1)

  As the phosphate, for example, a monovalent alkali metal phosphate (sodium dihydrogen phosphate, lithium dihydrogen phosphate, potassium dihydrogen phosphate), ammonium hydrogen phosphate, and aluminum hydrogen phosphate are used. A plurality of types can be appropriately selected and used. In addition, as the oxide, for example, one or a plurality of types from a group of divalent oxides can be appropriately selected and used. In addition to IIA group oxides such as magnesium oxide, barium oxide, and calcium oxide, IIB Zinc oxide which is a group oxide can also be used.

  In order to form a denser and smoother solidified body, it is also a preferable form to add a silicate and hybridize a silicate ceramic (for example, potassium silicate). As the silicate, for example, one or a plurality of types selected from the group of calcium silicate, magnesium silicate and barium silicate which are IIA group silicates, and sodium silicate and lithium silicate which are group IA silicates are used. be able to. The use of silicate is suitable when finishing treatment such as painting and polishing is omitted.

  In preparing solidified slurries, reused aggregates and pigments made from industrial waste such as fillers, aggregates (fine aggregates, coarse aggregates), earthenware slag, alumina, etc., as necessary Additives such as colorants, fibers such as synthetic fibers, silica fume fine powder, kaolinite, tie polymers, emulsifiers and anti-aggregation agents can be added.

  The amount of phosphate, oxide and silicate used as the solidifying component can be determined as appropriate, but in the dry powder state, 20 to 40 wt% is the oxide with respect to the total amount of the solidifying component and 25 to 45 wt%. It is preferable to use phosphate and 15 to 55 wt% silicate. Further, when producing a solidified slurry, a necessary amount of additives (for example, about 15 to 33 parts by weight) is added to 17 to 35 parts by weight of the solidified material, and a necessary amount of water is further added to obtain a final solidified slurry. The water content is preferably about 15 to 23 wt%, and the flowability according to the test based on ASTM C1437 is preferably about 40 to 140%.

<Molded body>
The molded body of the present invention can be produced by a known molding technique such as pouring and hardening the above-mentioned solidified slurry of the phosphate solidified material into a mold.

  The molded body is preferably a plate shape such as a tile, panel, siding board or the like, but may be a block shape having a certain thickness. The size is not particularly limited. For example, when processing a floor surface, the length × width × thickness can be about 50 mm to 600 mm × 50 mm to 600 mm × 3 mm to 30 mm. When performed, the length x width x thickness may be about 50 mm to 900 mm x 50 mm to 2000 mm x 3 mm to 30 mm.

  When the molded body is produced, the molded body can be colored by mixing a pigment or the like into the slurry or by coating the surface of the molded body. In this case, in addition to the color different from the adhesive for attaching the molded body, it can also be the same color.

  Further, irregularities such as patterns and letters can be imparted to the surface during the production of the molded body. And by using such a molded object, surface finish with high decorativeness can be performed like a tile.

<Construction>
In the present invention, the cured molded body by the above-described phosphate solidified material is attached to the target surface using the above-described phosphate solidified slurry as an adhesive, and the target surface is covered with the molded body. The present invention is not limited to the target surface, but can be used to form the surface of a building, such as a floor surface, an inner wall surface, an outer wall surface, a ceiling surface, a roof surface, and the like.

  In construction, the procedure can be determined as appropriate. For example, (1) as shown in FIG. 1, the solidified slurry 3 is applied to the back surface of the molded body 2 and repeatedly crimped to the target surface 1, and the molded bodies 2 are arranged side by side. Thus, after applying the solidified slurry 3 to a certain range of the target surface 1, the molded body 2 is aligned and pressure-bonded thereon. (3) As shown in FIG. In addition to the method of arranging and pressing the molded body 2 coated with the solidified slurry 3 on the back surface after being applied to the range, (4) as shown in FIG. 4, the molded body holder 5 (mold) facing the target surface 1 Frame, etc.), and after the molded body 2 is attached to the holder, a solidified slurry 3 is placed between the molded body 2 and the target surface 1 (this method is suitable for a wall surface). Can also be adopted. In addition, although drawing does not show until the solidification slurry 3 protrudes at the time of pressure bonding for easy understanding, the solidification slurry 3 wraps around the molded body 2 by pressure bonding in the examples shown in FIGS. The molded body 2 may be buried in the solidified slurry 3.

  After the construction, the target surface 1 is covered with a molded body 2 that has been cured in advance, and the solidified slurry 3 to be cast on site is hidden behind the molded body 2, so that moisture adheres to the solidified slurry 3 that is being cured on site. Even if it becomes white, it hardly appears on the surface and may appear on the joint, but even in that case, the appearance does not deteriorate. In addition, the code | symbol 3s in a figure has shown the part after hardening of a solidification slurry. Moreover, since there is no surface leveling over a wide range, construction is easy without requiring skill. In addition, since the molded body 2 and the adhesive are phosphate-based solidifying materials, they are completely integrated (the degree to which the base material is destroyed, not the interface destruction even if the molded body 2 is peeled off). Thus, the solidified slurry 3 is cast and the target surface 1 is covered, and an integrated surface layer having excellent characteristics as described above is formed. This is very different from cement-based solidified material. In addition, as with tiles, no ground treatment or primer is required. Nevertheless, when the molded body 2 is manufactured, if a pigment or the like is mixed into the slurry, or the surface of the molded body 2 is coated, or if the surface is provided with pattern irregularities, the surface finish is as highly decorative as the tile. be able to.

  When the molded bodies 2 are arranged side by side, it is desirable to perform joint filling as shown in FIG. 6, but as shown in FIG. 5, the joint filling may be omitted by burying the molded body 2 in the solidified slurry 3. it can. In particular, it is preferable to use the above-described solidified slurry 3 of the phosphate-based solidified material as the filler 4 for filling the joints because not only the molded body 2 and the adhesive but also the joints are completely integrated. Furthermore, in this case, after the filler 4 filled as shown in FIG. 6C is cured, the surface of the molded body 2 and the surface of the joint are integrally polished as shown in FIG. By making the surface of the body 2 and the surface of joints flush with each other, a smooth surface finish substantially free of joints can be performed. In addition, the code | symbol 4s in a figure has shown the part after hardening of a filler.

  Further, although not shown, it is possible to paste the molded body without any gaps to eliminate joints or to omit joints.

  The present invention can be applied to form a surface of a building or the like.
